In the year since I first wrote about kpatch, Red Hat’s live kernel patching project for Linux, we’ve been very busy. Here are some of the highlights from the last year of live kernel patching development, and some clues about where we may be headed in the future.
Red Hat Enterprise Linux 7 Special Interest Group
In 2014, we kicked off a kpatch Special Interest Group (SIG) for users who are interested in trying out kpatch in a Red Hat Enterprise Linux 7 environment. We’ve delivered kpatch fixes for several kernel CVEs, allowing users to easily apply fixes to their kernels immediately with no disruption or reboots necessary.
If you’re a Red Hat Enterprise Linux customer and are interested in joining the kpatch SIG

Over the last 18 months, especially since the general availability of Red Hat Enterprise Linux 7, “containers” have emerged as a hot topic. With the more recent introduction of Red Hat Enterprise Linux Atomic Host, an operating system optimized for running the next generation of applications with Linux containers, one might wonder… what about virtualization? In that the benefits of containerization seem to overlap those of traditional virtualization, how do organizations know when to pick one approach over the other?

This post is dedicated to the new SSSD features in Red Hat Enterprise Linux 7.1 that have significance when SSSD is used by itself (i.e. without IdM integration) – for example, when connecting directly to Active Directory (AD) or some other Directory Server.
Control Access to Linux Machines with Active Directory GPO
A common use case for managing computer-based access control in an Active Directory environment is through the use of GPO policy settings related to Windows Logon Rights. The Administrator who maintains a heterogeneous AD and Red Hat Enterprise Linux network without an IdM server has traditionally had to face the challenging task of centrally controlling access to the Linux machines without being able to update the SSSD configuration on each and every client machine.
In Red Hat Enterprise Linux 7.1, the Administrator is (now) able to

Red Hat’s Performance Engineering team is responsible for the performance of many of Red Hat’s products. We cover existing products such as Red Hat Enterprise Linux, OpenStack Platform, OpenShift and Red Hat Enterprise Virtualization, as well as newer products like Ceph and CloudForms.
Although these days we contribute extensively to Red Hat’s cloud offerings, Red Hat Enterprise Linux remains a core responsibility as the building block for our ecosystem of customers and partners, plus much of Red Hat’s growing product portfolio.
Prior to beginning efforts on Red Hat Enterprise Linux 7 in earnest

Having access to quality random numbers is essential for correct and secure operation of operating systems. Operating systems need random numbers from an entropy pool for a variety of tasks, like creating secure SSH or GPG/PGP keypairs, generating random PIDs for processes, generating TCP sequence numbers, and generating UUIDs.
With Red Hat Enterprise Linux 7 we introduced the virtio RNG (Random Number Generator) device that provides KVM virtual machines access to entropy from the host machine. Red Hat Enterprise Virtualization starting version 3.5 also has exposed this feature. We have since made improvements to Red Hat Enterprise Linux guests to make the feature easier and more straightforward to use.
A Brief Introduction to virtio and Paravirtualized Devices
virtio is the paravirtualized transport framework for KVM virtual machines. Using the virtio framework, new devices can be

Today marks an exciting milestone for Red Hat as we share news of the general availability of Red Hat Enterprise Linux 7 Atomic Host, an operating system optimized for running the next generation of applications with Linux containers.
Based on the world’s leading enterprise Linux platform, Red Hat Enterprise Linux Atomic Host enables enterprises to embrace a container-based architecture to take advantage of the benefits of development and deployment flexibility and simplified maintenance, without sacrificing performance, stability, security, or the value of Red Hat’s vast certified ecosystem.
An application architecture based on Linux containers requires not only the tools to build and run containers, but also an underlying foundation that is secure, reliable, enterprise-grade, with an established lifecycle designed to meet the ongoing requirements of the enterprise over the long term. The release of Red Hat Enterprise Linux Atomic Host supports Red Hat’s commitment to make Linux containers a stable and reliable component of enterprise IT across the open hybrid cloud.
Red Hat Enterprise Linux 7 Atomic Host provides many benefits, including
